What effect does hypothyroidism and hyperthyroidism have on the fetus during pregnancy and how to control it?

Hyperthyroidism during pregnancy has an impact on the fetus, and more importantly, the fertility of hyperthyroidism patients is obviously affected. If pregnant women suffer from hyperthyroidism, improper control of hyperthyroidism not only affects their own health, but also does great harm to the development of the fetus.

Affect the normal process and outcome of pregnancy: Generally speaking, patients with hyperthyroidism will have miscarriage, stillbirth and premature delivery due to improper treatment or no treatment. The abortion rate is as high as 26%, and the probability of premature delivery is 15%. These risks are much higher than those of pregnant women, who may change their mood, thus aggravating hyperthyroidism symptoms and diseases. For patients with hyperthyroidism during pregnancy or unexpected pregnancy, we should be vigilant, actively accept treatment, control hyperthyroidism and have a healthy pregnancy.

Hypertension: The probability of hyperthyroid pregnant women suffering from pregnancy-induced hypertension is 10 times that of normal pregnant women. If hyperthyroidism is not well controlled, it may lead to thyroid crisis. Although these cases are not common, they are dangerous and fatal. Fetal malformation: Hyperthyroid newborns are more likely to have overweight babies and premature babies. The mortality rate of newborns and perinatal infants is higher than that of ordinary pregnant women, and the incidence of fetal malformation is also higher than that of ordinary pregnant women.

Children with congenital diseases: children born to hyperthyroidism pregnant women can have congenital hyperthyroidism in the fetus through the placenta because of the existence of long-acting thyrotropin in the mother. In addition, hyperthyroidism treatment leads to congenital hypothyroidism by inhibiting fetal thyroid function.

Clinically, most pregnant women with hyperthyroidism can give birth to healthy children by actively receiving effective treatment. However, it is suggested that women who have a pregnancy preparation plan should do a good job of pre-pregnancy examination, eliminate risks in time and reduce subsequent health risks. For women with hyperthyroidism, it is not recommended to get pregnant within the scope of the disease. It is best to wait until hyperthyroidism is cured before planning pregnancy. In addition, women with a history of hyperthyroidism should pay special attention to the control of thyroid function during pregnancy, so as to avoid the recurrence of hyperthyroidism during pregnancy and the lack of timely treatment, which will affect pregnancy.
